Galatians 4:18-22

But it is good to be zealously affected always in a good thing, and not only when I am present with you.

My little children, of whom I travail in birth again until Christ be formed in you,

I desire to be present with you now, and to change my voice; for I stand in doubt of you.

Tell me, ye that desire to be under the law, do ye not hear the law?

For it is written, that Abraham had two sons, the one by a bondmaid, the other by a freewoman.
